Abstract (en)
[origin: WO2020206029A1] In a bi - directional screwdriver, the screwdriver may include a handle, a main housing, and a gearing assembly, which is mounted on the idle gear axle on the transmission seat and is fitted between the driving gear and the driven gear for transferring motion. When the grip ring is gripped and the handle is rotated to rotate the driving gear, the driving gear may rotate the driven gear in a reverse direction through the idle gear. The screwdriver may include a reversing means which can include a reversing member, a pawl, and a direction collar, in which the driving gear, the driven gear, and the transmission seat are all sleeved on the main housing. The reversing member may be sleeved into the main housing and able to rotate the main housing. The direction collar may engage with and rotate the reversing member, causing a change of output direction.
